Aqualab Automated Water Quality Analyser

The Aqualab provides water quality managers with a cost effective, reliable alternative to all presently available methods of water analysis.

The Aqualab system performs a wide range of chemical and physical analysis regimes, automatically and unattended in the field, with a level of performance equivalent to certified laboratory analysis.

Real time measurement and validation of field analyses by on-board reference standards delivers an unmatched level of confidence in the results obtained.

The precision performance of Aqualab is provided at a fraction of the cost-per-analysis of a typical grab sampling and laboratory analysis program.

The Aqualab is complemented by a range of optional installation and communication packages. For monitoring programs in seawater, rivers, dams, lakes or in industrial environments, the Aqualab can be configured for optimum performance to meet site specific conditions. Remote control of all operating parameters and data retrieval are available with all of the communication package options.

System versatility is enhanced by software which enables users to pre-set monitoring intervals, trigger levels and alarm functions. Users can automatically obtain the most valuable data during significant events. System interrogation and programming of individual sensor monitoring frequencies can be conducted at any time. On-board data storage provides additional systems support to the facility of remote retrieval and computer storage of results.

Aqualab capabilities include:

	In-situ and unattended analysis with remote computer control of operating parameters. Data storage of results obtained in real time.
	Laboratory standard detection limits obtained by calibration with on-board reference standards.
	Low total energy demand which permits long term continuous field operation.
	Analytical system and multiple intake lines backflushed and cleaned automatically.
	Suitable for operation with high sediment load or dirty waters.
	Choice of programmable monitoring regimes including event and alarm triggering.
	Single or multiple intake lines which can be fixed or floating. Provides for continuous monitoring programs at several point locations.
	Packaging and installation options to meet a variety of site conditions.
	Communication options cover all facilities for data transfer and system control by cellular phone, radio and satellite.
	Windows based user interface which provides graphical and tabular results display on a remote PC terminal.

Results Validation with On-Board Chemistries

The on-board reagent packages include both low and high range concentrations of standard solutions for the determination of unknown sample concentrations in the analysis of Reactive Phosphate, Ammonia and Nitrate. Results are confirmed directly in the field in the same manner as standard laboratory procedures.

Also, single reference standards for confirmation of sensor performance in the determination of pH and Electrical Conductivity are included.

In addition, the Aqualab includes on-board chemical reagents required for sample modifications (adjusts pH to greater than 11) in the analysis of Ammonia. Also included are the reagents for ortho-Phosphate determination, based on a reaction which forms a Phospho-Molybdate (blue colour) complex, the same chemistries as performed in the standard laboratory method.

De-Ionised water and a cleaning solution complete the chemical reagents packages. The system will automatically backflush and clean the analytical train and intake lines ensuring a clean system between analyses.

Results Verification with Optional Sample Collection System

The Aqualab includes an "intelligent" water sampling system which will automatically retain samples based on your specified critical parameter results for up to 24 levels of trigger values. Time-based sampling is also included. The Water Sampler will not only collect and seal your sample and send positive identification to your data terminal, it will also add a preservative agent to retain sample integrity. A variety of sample sizes and bottles enhances system versatility.

Aqualab Installation Options

The Aqualab is designed to perform analyses on waters which range in quality from drinking water to polluted effluent's (of low oil content) to silt laden seawater. A wide range in user monitoring schedules requires a range of installation packages to suit specific site conditions.
